LOCOMOTlVE-FURNACE.

SPECIFICATION forming part of Letters Patent No. 246,072, dated August23, 1881,

Application filed January 12, 1881. (No model.) i

.T 0 all whom'it may concern Be it known that I, THOMAS A. BUCKLAND, ofSt. Louis, Missouri, have made a new and useful Improvement inLocomotive-Furnaces, of which the following is a full, clear, and exactdescription, reference being bad to the annexed drawings, making part ofthis specification, in which- Figure 1 is a view in perspective, showingthat portion of a locomotive with which the improvement in question isimmediately connected, the shell of the furnace-chamber being brokenaway to exhibit the interior construction; and Fig. 2, a detail, being ahorizontal section taken through the forward end of the furnacechamber,the section passing through the vertically-arranged tiling at theforward end of the furnace, but below the level of the forward end ofthe diaphragm.

The same letters denote the same parts.

The improvement relates to the system of tiles employed in thefurnace-chamber; and it consists in the combination of a set of tilesarranged vertically at and around the forward end of thefurnace-chamber, and a sloping tile the upper end of which rests againstthe rear or door wall of the furnace-chamber and the lower end againstthe vertically-arranged tiles, the various tiles being shaped andarranged, more particularly described, as follows:

A represents the furnace-chamber, of the usual construction, B B beingthe wallof the furnace, G the doorway to the furnace, D the grate, and Ethe inlets to the flues.

At the forward end of the furnace-chamber is a tile, FF, preferably intwo parts, as shown. It rests upon across'iron, G, or upon the grate D,and extending upward to the lines, the upper ends of the tile beingpreferably shaped to conform to the location of the lines, being higherat the sides of the furnace-chamber than at the center, as seen in Fig.1.

H H represent tiles, arranged respectively at each side of thefurnacc-chai'nber, being supported underneath by any suitable means,(not shown,) and, if desired, resting upon the grate. The forward ends,h h, of the tiles are held in olfsetsffin the tile F F. The rear ends,it h,

of the tiles H H are battered.

I represents a tile-diaphragm, preferably in two or more parts, i 6. Itsupper rear end rests against the rear wall, B, of the chamber. Itsforward lower end rests against the rear ends, h h, of the tiles H H,operating to brace the latter longitudinally against the tile F F, andthe tiles F F H H, in turn, operating to uphold the diaphragm, thesloping ends it h preventing the forward end of the diaphragm fromdropping. The center 2" of the lower end of the diaphragm projectsbetween the inner sides of the tiles H H, to keep the latter laterallyin place. When thediaphragm I is in two or more pieces the variouspieces may be arched together, so as to act as one part against thetiles H Hthat is, if the diaphragm is divided longitudinally the arch isturned transversely in the furnace-chamber, and if divided transverse] ythe arch is turned longitudinally in the furnace-chamber. If the parts ii are perfectly flat, as shown, the central portion of the diaphragm maybe supported by a cross water-tube. (Not shown.)

If desired, the tiles H F can be connected by a miter-joint, as shown at71/3, Fig. 1, and, instead of battering the ends h h of the tiles H H,the latter may be notched, as shown at 1 Fig. 1, and the diaphragm Iinserted in the notch.

The system of tiling, F H I, forms a throat, J, at the forward end ofthe furnace-chamber, in which the fuel is more perfectly burned and ahigher degree of heat attained than in the ordinaryfurnace-chamber.These results may be further improved by admitting air through theperforations f h in the tiles F H. The chief advantage, howe 'er, of'theimprovement is that the various parts of the system of tiling can beeasily made, readily set up in place, and when set up in thefurnace-chamber they coact to keep each of the parts permanently inposition.

1 claim- The furnace-chamber A, having the tiles F F H H I and I,combined, arranged, and held substantially as described.
